Complete Atrium Glazing Refurbishment
Full-scale overhaul of ageing overhead glazing systems. We restore commercial atriums to weathertight, energy-efficient performance — extending their lifespan by decades.
When Is Full Refurbishment the Right Choice?
Most commercial atrium glazing systems have a design life of 25-35 years, but many begin to show significant deterioration well before that point. When an atrium reaches the stage where individual repairs are becoming frequent and costly, a full system refurbishment is almost always more economical than continued piecemeal maintenance. Key indicators include widespread sealant failure across multiple joints, corroded or degraded glazing bar cappings, multiple failed glass units, persistent leaks that recur after repair, and visible deterioration of the structural framework.
A full refurbishment addresses every component of the glazing system simultaneously, eliminating the cycle of reactive repairs and delivering a comprehensive, guaranteed solution. It also provides the opportunity to upgrade glass specifications, improve thermal performance and bring the system into compliance with current Building Regulations — all of which add significant value to the building.
Our Refurbishment Process
Every full refurbishment begins with a comprehensive condition survey that assesses every component of the glazing system: framework, glazing bars, cappings, sealants, gaskets, glass units, drainage and flashings. This survey forms the basis of a detailed specification and scope of works that is agreed with the client before any work commences.
The refurbishment itself typically follows a systematic bay-by-bay approach, working across the atrium in planned sections to maintain weathertight integrity throughout the project. Each section is stripped back to the structural framework, with all sealants, gaskets and cappings removed. The framework is inspected, repaired where necessary and treated with protective coatings. New high-performance sealants, gaskets and cappings are installed, failed glass units are replaced, and the drainage system is overhauled. The result is a glazing system that performs as well as — or better than — when it was originally installed.
Extending Your Atrium's Lifespan
A properly executed refurbishment can extend the functional lifespan of an atrium glazing system by 20-30 years, representing exceptional value compared to the cost of full system replacement. Modern sealant technologies, improved gasket materials and upgraded glass specifications all contribute to significantly better long-term performance than the original installation.
We also design and install improved drainage details where the original system design is inadequate — a common issue with atriums built before current best-practice guidelines were established. Enhanced drainage capacity and improved water management reduce the risk of future leaks and extend the intervals between maintenance visits.

Shopping Centre — Full Barrel-Vault Atrium Refurbishment
The Challenge
Complete refurbishment of 2,400m² of barrel-vault atrium roofing suffering from widespread sealant failure, corroded cappings and 47 failed glass units. The centre remained fully operational throughout.
The Result
All glazing bar joints stripped and resealed, 47 glass units replaced with upgraded solar control units, drainage system completely overhauled, and all cappings replaced. Project completed in 12 weeks with zero disruption to trading. 25-year insurance-backed guarantee provided.
Frequently Asked Questions
Duration depends on the size and complexity of the atrium. A typical medium-sized commercial atrium (500-1,500m²) takes 8-16 weeks. Larger structures such as shopping centre atriums may take 16-24 weeks. We provide detailed programme schedules as part of every quotation.
Yes. We routinely carry out full refurbishments in live, occupied buildings including busy shopping centres and corporate offices. Our bay-by-bay approach maintains weathertight integrity throughout, and we schedule noisy or disruptive activities out-of-hours where required.
In most cases, significantly so. A full refurbishment typically costs 40-60% less than complete system replacement while delivering comparable performance and lifespan. It also avoids the major disruption and extended timescales associated with full replacement.
All refurbishment works are fully guaranteed, and we offer insurance-backed guarantees (IBGs) of up to 25 years on comprehensive refurbishment projects. This provides long-term protection and peace of mind for building owners and facilities managers.
Yes. Refurbishment provides the opportunity to upgrade glass specifications, improve seal integrity and enhance the overall thermal performance of the glazing system. Many clients see measurable reductions in heating and cooling costs following a comprehensive refurbishment.
